When I think of a straw house, I imagine three little pigs and a nasty wolf. But of course, straw houses only exist in fairy tales, right?

Think again. Check out Felix Jerusalem’s Stroh Haus in Switzerland. This cool (and literally green) house is made from compressed straw bales that serve two distinct purposes: not only do they provide the building’s exterior surface (beneath a translucent siding), they serve as the structure’s soundproofing insulation.
